"Unable to resolve slug into ID (no matches)"

### Describe the problem

"foamfix-for-minecraft"s slug has appeared to have changed to "foamfix-optimization-mod" which is forcing the container to exit. When I try to exclude foamfix-for-minecraft nothing changes. I attempted to create another container using AUTO_CURSEFORGE using ATM9 and got the same error with foamfix.



### Container definition

```

Reproduce the failure with the shown Docker Compose settings, especially CF_EXCLUDE_MODS and CF_PAGE_URL. Start at CurseForgeInstaller.resolveExcludeIncludes and CurseForgeApiClient.slugToId from the stack trace, then verify that the excluded FoamFix project is resolved without aborting modpack installation.
